We are all online. We rarely leave our homes - only when necessary, even though, at times, the prescribed measures allow us to do so. Our daily routines are embedded in video calls and performed online. Household members are forced to stay together now more than ever, but at the same time, all of them need space to study and work. A sudden transition from classrooms to Zoom rooms is forcing us to rethink the entire educational system: New educational grammar is needed! The need for additional insulation inside apartments has become a reality. A wardrobe turns into a study, and nature becomes our balcony. How aware are we of the current changes in our living spaces? Can we use architecture to establish a dialogue with contemporary issues and events, and provide critical solutions that would make the spaces we live in better? New spatial grammar is needed! The Covid-19 pandemic and rapid digitalisation have impacted architecture that has traditionally been a very slow discipline which uses specific tools with manual designing and thinking processes. Architectural education has seen demand-driven changes in the learning process through the years. Following the switch from the system inherited from the socialist period to the Bologna system, the impact of the pandemic has called for the need to conform to changes in teaching methods and understanding of space.

The paper emphasizes that the period of beginning study is alarming, because through the new life circumstances, obligations and environment, great changes occur and a personal hierarchy of values and priorities of students in their lives is formed. The aim of the research was to determine eating habits and differences in relation to gender among students at the University of Tuzla. The research was conducted on a sample of 813 respondents, male and female students of the University of Tuzla. Eating attitude test (EAT26) is used for diagnosis of eating habits. Obtained results sowed statistically significant difference between male and female students in the applied test EAT26. Key words: EAT26, eating habits, students

This chapter provides an overview of research opportunities and issues in IoT forensics. It gives a quick introduction to forensics and digital forensics. Key specifics of IoT forensics are explained. Issues that arise from IoT related challenges in all phases of a forensic investigation are presented. Some opportunities that IoT brings to forensics are pointed out. An example of an IoT forensics case is provided. A detailed research overview is given, providing information on the main research directions with a brief overview of relevant papers. The chapter concludes with some ideas for future research.

The aim of this study was to determine metric characteristics of the Test of Gross Motor Development (TGMD 3). The study included 146 children from Bosnia and Herzegovina, aged 3-10,4 (6,80 ± 2,23 years; 46,6% male; 53,4% females). Based on the obtained research results it can be concluded that Test of Gross Motor Development (TGMD-3) has satisfactory reliability and internal consistency for children aged 3 to 10 years. Mutual correlations confirm the homogenity of the scale. Based on results of Kolmogorov-Smirnov test, Test of Gross Motor Development is not sensitive for subjects included in this study. The obtained results of the confirmatory factor analysis of this model show a partial agreement of the assumed model with the data ( h2 = 108.17, df = 64, h2 / df = 1.69, TLI = 0.86, CFI = 0.72, NFI = 0.72., RMSEA = 0.07 CI = 0.04-0.09). The data was analyzed with the SPSS 20 software (with the AMOS package). The limitations in the research are the respondents, because due to the epidemiological situation caused by COVID 19, a convenience sample of respondents was selected. Key words: Motor development, TGMD 3, childhood, reliability, confirmatory factor analysis.

Modelling of flicker in large real distribution networks has been a challenge until now, due to huge number of flicker sources contributing to total flicker levels in the network. In this paper, voltage flicker is modelled for a large real medium voltage (MV) distribution network. The total flicker is calculated from background flicker resulting from high voltage network and from flicker emission of a large number of sources in the analysed MV network. The flicker emission was modelled by statistical distributions of emission levels. Results of the simulation were compared to flicker measurements from several power quality monitors, installed in the feeders of the analysed MV network. The results show a significant similarity between the model and the measurements. Conclusion of this work is that the voltage flicker can be modelled with sufficient accuracy, even in large real MV networks.

In this paper, the tradeoff between spectrum efficiency (SE) and energy efficiency (EE) is investigated in terms of interference management and power allocation for heterogeneous networks (HetNets) with non-orthogonal multiple access (NOMA). The EE and SE tradeoff is modeled as a multi-objective problem (MOP) under the maximum power and quality of service (QoS) constraints, which is non-convex. The MOP is relaxed into a convex single objective problem (SOP) by adopting a weighted sum strategy with the hypograph transformation. The SOP is solved in two steps. In the first step, we propose a power allocation technique based on non-cooperative (NC) game for EE and SE in NOMA HetNets. In the proposed NC game, the macro base station (MBS) and the small BSs (SBSs) compete with an equal priority in order to optimize their transmit powers towards maximizing the weighted sum of SE and EE. In the second step, a closed-form formula is proposed to control the power allocated to users taking into account both QoS constraint and successive interference cancellation (SIC) condition. From simulations, the proposed technique can, in some dedicated settings, considerably improve the tradeoff between EE and SE over conventional techniques.

The paper presents a procedure for numerical modelling of the rod cross-section bearing capacity. Equilibrium between cross sectional forces and cross-sectional stresses is determined by iterative procedures. According to the described procedure, the load-bearing capacity of the cross-section is determined according to the isotropic linear and nonlinear behavior of the material, for homogeneous and inhomogeneous cross-sections. The nonlinear behavior of the material reduces the stiffness of the cross section of the rod EA and EI, with a significant increase in the deformation values ε and κ. The applicability of the calculation and analysis of obtained results is presented using numerical examples.
